Chemical Production Solutions | 178+ Plants Delivered

At Changzhou Sanli Tech International Trade Co., Ltd., we understand that chemical production is not merely about individual unit operations but a complex, integrated system demanding seamless coordination. Our chemical production solutions are built upon a foundation of over 172 complete sets of proprietary technologies, ranging from the Methanol Industry’s Formaldehyde (Fe-molybdenum and Silver Method) plants to advanced New Materials like the Polysulfone Plant. We serve as a one-stop partner, guiding clients from initial consultation through to full-scale production. For a client in the specialty chemicals sector seeking to establish a greenfield facility for Methylal via Pressure Swing Distillation, our solution begins with a deep analysis of feedstock availability and market demands, followed by the delivery of a customized process engineering package. Our solutions are particularly impactful in the Ethylene Industry, where we provide integrated plants for EO (Ethylene Oxide), MEG, and downstream derivatives like EOA and ETX, ensuring high-purity outputs and energy efficiency. By integrating system integration with full process development, and leveraging our R&D collaboration with the Institute of Process Engineering of the Chinese Academy of Sciences, we de-risk projects from the outset. Whether it’s a complex POM (Polyformaldehyde) plant or a specialized DMMn (Polyoxymethylene Dimethylether) unit, our solutions are engineered for profitability, reliability, and long-term operational excellence, ensuring that each plant runs smoothly and adds significant value to the customer’s factory.
